1" 0 all whom it may concern:

1 Be it known that I, CrrAnLns 0. Bosses, a

citizen of. the United States, residing at herein. The frame of such apump com- Atlantic, county of Norfolk, State of Massachusetts, haveinvented an Improvement in Power Pumping Units, of which the followingdescription, in connection with the accompanying drawing, is aspecification, like characters on the drawing representing'like parts.This invention relates to a power pumping unit or a self containedstructure comprising a pump. and a motor for operating the pump. Such aunit renders the pump capable of beingset up in any desired locality andto be readily operated under power to pump a large volume ofwater.

=The object of the invention is to present a unit of this characterwhich shall be compact, and in which the elements shallbe so arranged asto present a well balanced structure having a low center of gravity.

The object of the invention is further to provide a construction inwhich a standard form of hand pump may be utilized in the "unit, and inwhich the construction addedto the pump results in a complete structureof power pumping unit which is well balanced and has a low center ofgravity. 1 These and other features of the invention will appear morefully from the accompany- .ing description and drawings, and will beparticularly pointed out in the claims.

In the drawings:

Fig. 2 is a right hand end elevation of the construction shown in Fig.11..

Fig. 3 is a top plan view of the supporting frame forming a part oftheunit.

The pump employed in this unit may be of any standard construction andits mechanism forms no part of the present invention. A standard form ofhand pump is illustrated I monly includes a casing comprising a base. 1

and a top section 2, secured together by bolts 3 passing throughlugs iformed on the two parts of the casing; The pumpingmember may he of anytype and is herein shown as of the diaphragm type. The flexible diaphragm 5 is clamped at its periphery between the casing parts 1 and 2.The central portion of the diaphragm is clamped between metal rings 6and 7 in which is mounted the discharge valve 8. The clamping bolts 9for these rings extend upward and support a cross head 10. The inletofthe pump 11 is provided with a suction valve 12 and the dischargeoutlet is through a spout 13 atone side of the top casing 2. Such a handpump is usually operated by a handle engaging the cross head so thatwhen the handle is rocked, water is drawn in from the inlet 11 andpumped up through the diaphragm Valve 8 andout over the spout 13.

In the present invention there is provided a supporting frame 14 shownseparately in Fig. 3. This frame is secured in superimposed verticalrelation to the pump casing and provides the support for the motor andconnections necessary to complete the power pumping unit.

. This supporting frame comprises a bed. plate 15 and preferably adepending hollow base 16. The hollow base enables the frame to fit welldown over the pump casing and be secured to the pump casing intermediateits ends as upon the lugs 4-. In the construction illustrated thesupporting frame is of generally rectangular shape and the hollowdepending base 16 is provided with a bottom flange 17 cut away to fitclosely against the exterior surface of the top casing 2 of the pump.This flange rests upon the lugs 4 and may be secured in position by thebolts 3, suitable apertured bosses 18 being provided in the bottomflange for that purpose. In the construction illustrated there are foursets of lugs 4 arranged in substantially diametrically disposed pairsbut the supporting frame is connected to but three of these pairsbecause at the fourth position the frame is cut away as shown at 19 toprovide for the with the crank shaft uppermost, thus bringing the centerof gravity of the motor as low as possible.

The motor is balanced with respect to the pumping member by a crankshaft 24: and connecting parts. This crank shaft 2% extends transverselyof the supporting frame and is mounted in bearing blocks 25 bolted at 26to the frame.

The motor usually runs at a speed much greater than that at which thepump may be eff ciently operated. Consequently reduction drivingconnections are provided between the motor and crank shaft 24: and suchdriving connections are herein shown as a system of gears. These gearsare also arranged in balanced relation with respect to the pumpingmember. In the construction illustrated the shaft 22 of the motor isprovided at the rear with a pinion 27 meshing with a gear 28 on anauxiliary shaft 29. A pinion 30 on the shaft 29 in turn meshes with alarge gear 31 on a shaft 32 extending transversely of the frameintermediate and parallel to the shaft 22 of the motor and the crankshaft 24 At the front the shaft 32 carries a pinion 33 meshing with alarge gear .84 on the front end of the crank shaft 2a. This system ofgearing is so arranged that the pinions and gears in the rear sub--stantially balance the pinion and gear at the front with relation to thevertical axis of the pumping unit.

In order to provide a connection from the pumping unit to the crankshaft 24: and maintain a low center of gravity, this invention makes useof a walking beam construction. Thus'the connecting parts which arecomparatively light, enable the motor to be set as low as possible. Insuch a construction a vertical post 35 is supported in a boss 36 formedat the side of the supporting frame. T o the top of this post is pivotedat 37 a walking beam 38 which extends centrally above the pumping memberor axis of the pumping unit to a point above the crank shaft 24;. Thiswalking beam is linked to the crank of the crank shaft 24 by a link I")pivoted atel-O to the walking, beam. The walking beam is also linked tothe cross head '10 of the pumping member by a link ll pivoted at .2 tothe cross head and at 43 to the walking beam.

It will thusbe seen. that the invention presents a self containedstructure which may be readily transported from. place to place and setup at any desired. location and at onceput inoperation upon. theoperationof the motor. It will be seen thattheconstructicn is such asto. have a. very low center of; gravity, andthat the various elementsane,et e

so disposed with respect to the central vertical axis, as to be insubstantial balance. Thus the pump will function without the necessityof being held down or secured in place and without danger of beingtipped over. The supporting frame while disposed well down on the pumpcasing, is nevertheless so arranged as to permit the discharge from theusual spout 13 arranged at the top of the pump casing. The entirestructure is rigid and compact and of simple and durable construction.

If, for any reason, it is desired to use the pump as a. hand pump thelink ll may readily be disconnected from the cross head 10 and thesupporting frame disconnected from the lugs -l-.

Having thus described my invention, what I claim. as new and desire tosecure by Letters Patent, is:

A power pumping unit comprising a pump casing, a movable pumpingmember therein, a supporting frame in superimposed vertical relation tothe pump casing, a motor mounted on the frame at one side of the pumpingmember, a crank shaft mounted on the frame at the opposite side of thepumping member, reduction driving connections from the motor to thecrank shaft, a walking beam extending above the motor, centrally abovethe pumping member and above the crank shaft, pivoted to the frame,linked to the crank shaft and linked to the pumping member whereby theframe and parts supported thereby have a relatively low center ofgravity and are substantially balanced with respect to the vertical axisof the pump casing.

2. A power pumping unit comprising the construction defined in claim 1in which the supporting frame is dctachably secured to the pump casingand the link connection on the walking beam is detachably scoured to themovable pumping member whereby the supporting frame and the partssupported thereby may be attached to and removed from a standard pump.
